During resync, we always read all blocks,\nso if there is a read error, we simply over-write it with the good block that\nwe found (assuming we found one).\n\nNote that the recovery case still isn\u0027t handled in an interesting way. There\nis nothing useful to do for the 2-copies case. If there are 3 or more copies,\nthen we could try reading from one of the non-missing copies, but this is a\nbit complicated and very rarely would be used, so I\u0027m leaving it for now.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "4443ae10ca15d07922ceda622f03db8865fa3d13", "tree": "f1f0a6a82142effbdde93913d53596aeeacc9dc4", "parents": [ "220946c9018de74b952446e3a4dff1bfd4cbf310" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Fri Jan 06 00:20:28 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:34:05 2006 -0800" }, "message": "[PATCH] md: auto-correct correctable read errors in raid10\n\nLargely just a cross-port from raid1.\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "6cce3b23f6f8e974c00af7a9b88f1d413ba368a8", "tree": "8c156f26a10de82b1626d74f810704cfd6f5ba2b", "parents": [ "b15c2e57f0f5bf596a19e9c5571e5b07cdfc7363" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Fri Jan 06 00:20:16 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:34:03 2006 -0800" }, "message": "[PATCH] md: write intent bitmap support for raid10\n\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "0a27ec96b6fb1abf867e36d7b0b681d67588767a", "tree": "4db5d9b8ef02b417fc2077d65311e2ea7cda5ce0", "parents": [ "17999be4aa408e7ff3b9d32c735649676567a3cd" ], "author": { "name": "NeilBrown", "email": "neilb@suse.de", "time": "Fri Jan 06 00:20:13 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Fri Jan 06 08:34:02 2006 -0800" }, "message": "[PATCH] md: improve raid10 \"IO Barrier\" concept\n\nraid10 needs to put up a barrier to new requests while it does resync or other\nbackground recovery.
